REPRODUCTIVE Flashcards
Spermatic cord
Each testis is suspended by a _____ within the scrotum.
Inguinal canal
As the testis descend, they pass through the _______________ of the abdominal wall into the scrotum.
Lobules
Connective tissue subdivides a testis into many _____________, which contain seminiferous tubules.
Epididymis
The ___________ is a highly coiled tube on the surface of the testis.
Spermatogenic
The _____________ cells of the epithelium that line the seminiferous tubule give rise to the sperm cells.
Meiosis
____________ is the process by which sperm cells are formed.
23
The number of chromosomes normally present in a human sperm cell is ____________
Epididymis
Sperm cells undergo maturation while they are stored in the __________.
Fructose
The secretion of the seminal vesicles is rich in the monosaccharide called ______________.
Prostate
The single __________ gland surrounds the urethra near the urinary bladder.
Bulbourethral
The secretion of the _____________ glands lubricates the end of the penis in preparation for sexual intercourse.
Glans penis
The sensitive, cone-shaped end of the penis is called the ______________.
Emission
_______________ is the movement of sperm cells and various glandular secretions into the urethra.
Ejaculation
________________ is the process by which semen is forced out through the urethra.
Scrotum
Encloses, protects, and regulates temperature of testes
Spermatogenic cell
Form mature sperms by the process of spermiogenesis
Interstitial cells (cells of Leydig)
Produce and secrete male sex hormones
Epididymis
Promotes sperm cell maturation; stores sperm cells; conveys sperm cells to ductus deferens
Corpora cavernosa and corpus spongiosum
- Two types of erectile tissue
- Hold blood involved in erection
Pelvic
The ovaries are located in the lateral wall of the ______ cavity.
Broad
The largest of the ovarian attachments is called the __________ ligament.
Ovarian follicles
The ovarian cortex appears granular because of the presence of _______________.
Oogenesis
The meiosis of egg formation is called ______________.
Coronal radiata
A primary oocyte is closely surrounded by epithelial cells called ___________ cells.
First polar body
when primary oocyte divides, a secondary oocyte and a _________ are produced.
FSH (follicle-stimulating hormone)
Primordial follicles are stimulated to develop into primary follicles by the hormone called _____________.
Ovulation
______________ is the process by which a secondary oocyte is released from the ovary.
Fallopian tubes
Uterine tubes are also called oviducts or ________________.
Infundibulum
The __________ is the funnel-shaped expansion at the end of a uterine tube.
Cervix
A portion of the uterus called the __________ extends downward into the upper portion of the vagina.
Endometrium
The inner mucosal layer of the uterus is called the _____________.
Smooth muscle
The myometrium is largely composed of _____________ tissue.
Smooth muscle
The myometrium is largely composed of _____________ tissue.
Hymen
The vaginal orifice is partially closed by a thin membrane called the __________.
Vulva
The group of external accessory organs that surround the openings of the urethra and vagina comprise the ___________.
Clitoris
The female organ that corresponds to the male penis is the _________.
Mons pubis
The rounded mass of fatty tissue overlying the pubic symphysis of the female is called the ____________.
Vestibular glands
The ____________________ of the female corresponds to the bulbourethral glands of the male.
Describe the function of the cilia in the lining of the uterine tube.
The cilia beat toward the uterus and help draw the secondary oocyte into the infundibulum of the tube and continue to move it towards the uterus.
Describe the fate of a mature antral follicle.
A mature follicle swells and ruptures under the influence of certain hormones. As this happens, the secondary oocyte
(egg cell) and follicular fluid escape from the ovary.
Briefly describe the changes that occur in the uterine lining during a reproductive cycle.
The uterine lining thickens and then it becomes granular and vascular. If fertilization does not occur, the lining disintegrates and sloughs off, creating menstrual flow.
